Why are the photos taken by astronauts on the moon not as bright as those we saw on earth?

In addition to the most beautiful moon, there are many nostalgic stars in the night sky. A little faint light can make people have infinite reverie, so the stars in the sky are a beautiful symbol of our wishes. In the quiet countryside, we can look up and see the stars all over the sky. However, it has also been suggested that when you see the photos taken by astronauts on the moon, the background is black and you can't see anything. Why? You can see it on earth.

In fact, you can see stars on the moon, and the night sky and stars on the moon are clearer than on the earth. The moon we only see from the photos of astronauts is only a small part, and the real universe is much more boundless. There is no starlight in the background of the image taken by the Chinese Lunar Rover Yutu, so we mistakenly think that we can't see anything on the moon, which is actually related to the performance of the camera.

The camera on Yutu is not wide enough, which makes the photos not very clear. If the photos taken by Yutu are processed by modern photo technology to improve the exposure, one or two light spots will be seen at the corners of the photos, which are the light of stars, that is to say, the stars are not invisible on the moon, but cannot be photographed by light. Because the appearance of the lunar rover is to photograph the surface of the moon and help record the image of the moon, and the surface of the moon has no atmosphere like the earth, so the brightness of the ground is higher than that of the earth, so the stars in the background can't be seen clearly when the machine focuses on the lunar rover.

The stars that can be seen on the earth can be seen on the moon and in space, but because of the low angle of reflected light and the low performance of the camera, you can't shoot the twinkling stars.
